Juan Ospina and Harald Uhlig have posted Mortgage-Backed Securities and the Financial Crisis of 2008: A Post-Mortem to SSRN. Given that the market for private-label MBS pretty much died by 2008, the title is apt. The paper presents a challenge to many of the standard narratives that have developed to explain the causes of the subprime crisis and the broader financial crisis that followed. Other researchers in this area will surely take up the gauntlet thrown down by this paper. Hopefully, we will collectively come up with the right narrative to explain the whole mess. The paper opens,

Gradually, the deep financial crisis of 2008 is in the rearview mirror. With that, standard narratives have emerged, which will inform and influence policy choices and public perception in the future for a long time to come. For that reason, it is all the more important to examine these narratives with the distance of time and available data, as many of these narratives were created in the heat of the moment.

One such standard narrative has it that the financial meltdown of 2008 was caused by an overextension of mortgages to weak borrowers, repackaged and then sold to willing lenders drawn in by faulty risk ratings for these mortgage back securities. To many, mortgage backed securities and rating agencies became the key villains of that financial crisis. In particular, rating agencies were blamed for assigning the coveted AAA rating to many securities, which did not deserve it, particularly in the subprime segment of the market, and that these ratings then lead to substantial losses for institutional investors, who needed to invest in safe assets and who mistakenly put their trust in these misguided ratings.

In this paper, we re-examine this narrative. We seek to address two questions in particular. First, were these mortgage backed securities bad investments? Second, were the ratings wrong? We answer these questions, using a new and detailed data set on the universe of non-agency residential mortgage backed securities (RMBS), obtained by devoting considerable work to carefully assembling data from Bloomberg and other sources. This data set allows us to examine the actual repayment stream and losses on principal on these securities up to 2014, and thus with a considerable distance since the crisis events. In essence, we provide a post-mortem on a market that many believe to have died in 2008. We find that the conventional narrative needs substantial rewriting: the ratings and the losses were not nearly as bad as this narrative would lead one to believe.

Specifically, we calculate the ex-post realized losses as well as ex-post realized return on investing on par in these mortgage backed securities, under various assumptions of the losses for the remaining life time of the securities. We compare these realized returns to their ratings in 2008 and their promised loss distributions, according to tables available from the rating agencies. We shall investigate, whether ratings were a sufficient statistic (to the degree that a discretized rating can be) or whether they were, essentially, just “noise”, given information already available to market participants at the time of investing such as ratings of borrowers.

We establish seven facts. First, the bulk of these securities was rated AAA. Second, AAA securities did ok: on average, their total cumulated losses up to 2013 are 2.3 percent. Third, the subprime AAA-rated segment did particularly well. Fourth, later vintages did worse than earlier vintages, except for subprime AAA securities. Fifth, the bulk of the losses were concentrated on a small share of all securities. Sixth, the misrating for AAA securities was modest. Seventh, controlling for a home price bust, a home price boom was good for the repayment on these securities. (1-2)

The Costs and Benefits of A Dodd-Frank Mortgage Provision

Craig Furfine has posted The Impact of Risk Retention Regulation on the Underwriting of Securitized Mortgages to SSRN. The abstract reads,

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 imposed requirements on securitization sponsors to retain not less than a 5% share of the aggregate credit risk of the assets they securitize. This paper examines whether loans securitized in deals sold after the implementation of risk-retention requirements look different from those sold before. Using a difference-in-difference empirical framework, I find that risk retention implementation is associated with mortgages being issued with markedly higher interest rates, yet notably lower loan-to-value ratios and higher income to debt-service ratios. Combined, these findings suggest that the implementation of risk retention rules has achieved a policy goal of making securitized loans safer, yet at a significant cost to borrowers.

While the paper primarily addressed the securitization of commercial mortgages, I was particularly interested in the paper’s conclusion that

the results suggest that risk retention rules will become an increasingly important factor for the underwriting of residential mortgages, too. Non-prime residential lending has continued to rapidly increase and if exemptions given to the GSEs expire in 2021 as currently scheduled, then a much greater fraction of residential lending will also be subject to these same rules.

As always, policymakers will need to evaluate whether we have the right balance between conservative underwriting and affordable credit. Let’s hope that they can address this issue with some objectivity given today’s polarized political climate.

Ghost of A Crisis Past

The Royal Bank of Scotland settled an investigation brought by New York Attorney General Schneiderman arising from mortgage-backed securities it issued in the run up to the financial crisis. RBS will pay a half a billion dollars. That’s a lot of money even in the context of the settlements that the federal government had wrangled from financial institutions in the aftermath to the financial crisis. The Settlement Agreement includes a Statement of Facts which RBS has acknowledged. Many settlement agreements do not include such a statement, leaving the dollar amount of the settlement to do all of the talking. We are lucky to see what facts exactly RBS is “acknowledging.”

The Statement of Facts found that assertions in the offering documents for the MBS were inaccurate and the securities have lost billions of dollars in collateral. These losses led to “shortfalls in principal and interest payments, as well as declines in the market value of their certificates.” (Appendix A at 2)

The Statement of Facts outlines just how RBS deviated from the statements it made in the offering documents:

RBS’s Representations to Investors

11. The Offering Documents for the Securitizations included, in varying forms, statements that the mortgage loans were “originated generally in accordance with” the originator’s underwriting guidelines, and that exceptions would be made on a “case-by-case basis…where compensating factors exist.” The Offering Documents further stated that such exceptions would be made “from time to time and in the ordinary course of business,” and disclosed that “[l]oans originated with exceptions may result in a higher number of delinquencies and loss severities than loans originated in strict compliance with the designated underwriting guidelines.”

12. The Offering Documents often contained statements, in varying forms, with respect to stated-income loans, that “the stated income is reasonable for the borrower’s employment and that the stated assets are consistent with the borrower’s income.”

13. The Offering Documents further contained statements, in varying forms, that each mortgage loan was originated “in compliance with applicable federal, state and local laws and regulations.”

14. The Offering Documents also included statements regarding the valuation of the mortgaged properties and the resulting loan-to-value (“LTV”) ratios, such as the weighted-average LTV and maximum LTV at origination of the securitized loans.

15. In addition, the Offering Documents typically stated that loans acquired by RBS for securitization were “subject to due diligence,” often described as including a “thorough credit and compliance review with loan level testing,” and stated that “the depositor will not include any loan in a trust fund if anything has come to the depositor’s attention that would cause it to believe that the representations and warranties of the related seller regarding that loan will not be accurate and complete in all material respects….”

The Actual Quality of the Mortgage Loans in the Securitizations

16. At times, RBS’s credit and compliance diligence vendors identified a number of loans as diligence exceptions because, in their view, they did not comply with underwriting guidelines and lacked adequate compensating factors or did not comply with applicable laws and regulations. Loans were also identified as diligence exceptions because of missing documents or other curable issues, or because of additional criteria specified by RBS for the review. In some instances, RBS disagreed with the vendor’s view. Certain of these loans were included in the Securitizations.

17. Additionally, some valuation diligence reports reflected variances between the appraised value of the mortgaged properties and the values obtained through other measures, such as automated valuation models (“AVMs”), broker-price opinions (“BPOs”), and drive-by reviews. In some instances, the LTVs calculated using AVM or BPO valuations exceeded the maximum LTV stated in the Offering Documents, which was calculated using the lower of the appraised value or the purchase price. Certain of these loans were included in the Securitizations.

18. RBS often purchased and securitized loans that were not part of the diligence sample without additional loan-file review. The Offering Documents did not include a description of the diligence reports prepared by RBS’s vendors, and did not state the size of the diligence sample or the number of loans with diligence exceptions or valuation variances identified during their reviews.

19. At times, RBS agreed with originators to limit the number of loan files it could review during its due diligence. Although RBS typically reserved the right to request additional loan-level diligence or not complete the loan purchase, in practice it rarely did so. These agreements with originators were not disclosed in the Offering Documents.

20. Finally, RBS performed post-securitization reviews of certain loans that defaulted shortly after securitization. These reviews identified a number of loans that appeared to breach the representations and warranties contained in the Offering Documents. Based on these reviews, RBS in some instances requested that the loan seller or loan originator repurchase certain loans. (Appendix A at 4-5)

Some of these inaccuracies are just straight-out misrepresentations, so they would not have been caught at the time by regulators, even if regulators had been looking. And that’s why, ten years later, we are still seeing financial crisis lawsuits being resolved.

It is not clear that these types of problems can be kept from infiltrating the capital market once greed overcomes fear over the course of the business cycle. That’s why it is important for individual actors to suffer consequences when they allow greed to take the driver’s seat. We still have not figured out how to effectively address tho individual actions that result in systemic harm.

Credit Risk Transfer and Financial Crises

Susan Wachter posted Credit Risk Transfer, Informed Markets, and Securitization to SSRN. It opens,

Across countries and over time, credit expansions have led to episodes of real estate booms and busts. Ten years ago, the Global Financial Crisis (GFC), the most recent of these, began with the Panic of 2007. The pricing of MBS had given no indication of rising credit risk. Nor had market indicators such as early payment default or delinquency – higher house prices censored the growing underlying credit risk. Myopic lenders, who believed that house prices would continue to increase, underpriced credit risk.

In the aftermath of the crisis, under the Dodd Frank Act, Congress put into place a new financial regulatory architecture with increased capital requirements and stress tests to limit the banking sector’s role in the amplification of real estate price bubbles. There remains, however, a major piece of unfinished business: the reform of the US housing finance system whose failure was central to the GFC. Fannie Mae and Freddie Mac, the government-sponsored enterprises (GSEs), put into conservatorship under the Housing and Economic Recovery Act (HERA) of 2008, await a mandate for a new securitization structure. The future state of the housing finance system in the US is still not resolved.

Currently, US taxpayers back almost all securitized mortgages through the GSEs and Ginnie Mae. While pre-crisis, private label securitization (PLS) had provided a significant share of funding for mortgages, since 2007, PLS has withdrawn from the market.

The appropriate pricing of mortgage backed securities can discourage lending if risk rises, and, potentially, can limit housing bubbles that are enabled by excess credit. Securitization markets, including the over the counter market for residential mortgage backed securities (RMBS) and the ABX securitization index, failed to do this in the housing bubble years 2003-2007.

GSEs have recently developed Credit Risk Transfers (CRTs) to trade and price credit risk. The objective is to bring private market discipline to bear on risk taking in securitized lending. For the CRT market to accomplish this, it must avoid the failures of financial assets to price risk. Are prerequisites for this in place? (2, references omitted)

Wachter partially answers this question in her conclusion:

CRT markets, if appropriately structured, can signal a heightened likelihood of systemic risk. Capital markets failed to do this in the run-up to the financial crisis, due to misaligned incentives and shrouded information. With sufficiently informed and appropriately structured markets, CRTs can provide market based discovery of the pricing of risk, and, with appropriate regulatory and guarantor response, can advance the stability of mortgage finance markets. (10)

Credit risk transfer has not yet been tested by a serious financial crisis. Wachter is right to bring a spotlight on it now, before events in the mortgage market overtake us.

Hope for the Securitization Market

The Structured Finance Industry Group has issued a white paper, Regulatory Reform: Securitization Industry Proposals to Support Growth in the Real Economy. While the paper is a useful summary of the industry’s needs, it would benefit from looking at the issue more broadly. The paper states that

One of the core policy responses to the financial crisis was the adoption of a wide variety of new regulations applicable to the securitization industry, largely in the form of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”). While many post-crisis analysts believe that the crisis laid bare the need for meaningful regulatory reform, SFIG members believe that any such regulation must: ƒ

  • Reduce risk in a manner such that benefits outweigh costs, including operational costs and inefficiencies; ƒ
  • Be coherent and consistent across the various sectors and across similar risk profiles; ƒ
  • Be operationally feasible from both a transactional and a loan origination basis so as not to compromise provision of credit to the real economy; ƒ
  • Be valued by key market participants; and ƒ
  • Be implemented in a targeted way (i.e. without unintended consequences).

In this paper, we will distinguish between the types of regulation we believe to be necessary and productive versus those that are, at the very least, not helpful and, in some cases, harmful. To support this approach, we believe it is helpful to evaluate financial market regulations, specifically those related to securitization, under three distinct categories, those that are:

1. Transactional in nature; i.e., directly impact the securitization market via a focus on underlying deal structures;

2. Banking rules that include securitization reform within their mandate; and

3. Banking rules that simply do not contemplate securitization and, therefore, may result in unintended consequences. (3)

The paper concludes,

The securitization industry serves as a mechanism for allowing institutional investors to deliver funding to the real economy, both to individual consumers of credit and to businesses of all sizes. This segment of credit reduces the real economy’s reliance on the banking system to deliver such funding, thereby reducing systemic risk.

It is important that both issuers of securitization bonds and investors in those bonds align at an appropriate balance in their goals to allow those issuers to maintain a business model that is not unduly penalized for using securitization as a funding tool, while at the same time, ensuring investors have confidence in the market via “skin in the game” and sufficiency of disclosure. (19)

I think the paper is totally right that we should design a regulatory environment that allows for responsible securitization. The paper is, however, silent on the interest of consumers, whose loans make up the collateral of many of the mortgage-backed and asset-backed securities that are at issue in the bond market. The system can’t be designed just to work for issuers and investors, consumers must have a voice too.

Taking up Housing Finance Reform

photo by Elliot P.

I am going to be a regular contributor to The Hill, the political website.  Here is my first column, It’s Time to Take Housing Finance Reform Through The 21st Century:

Fannie Mae and Freddie Mac, the two mortgage giants under the control of the federal government, have more than 45 percent of the share of the $10 trillion of mortgage debt outstanding. Ginnie Mae, a government agency that securitizes Federal Housing Administration (FHA) and Veterans Affairs (VA) mortgages, has another 16 percent.

These three entities together have a 98 percent share of the market for new residential mortgage-backed securities. This government domination of the mortgage market is not tenable and is, in fact, dangerous to the long-term health of the housing market, not to mention the federal budget.

No one ever intended for the federal government to be the primary supplier of mortgage credit. This places a lot of credit risk in the government’s lap. If things go south, taxpayers will be on the hook for another big bailout.

It is time to implement a housing finance reform plan that will last through the 21st century, one that appropriately allocates risk away from taxpayers, ensures liquidity during crises, and provides access to the housing markets to those who can consistently make their monthly mortgage payments.

The stakes for housing finance reform today are as high as they were in the 1930s when the housing market was in its greatest distress. It seems, however, that there was a greater clarity of purpose back then as to how the housing markets should function. There was a broadly held view that the government should encourage sustainable homeownership for a broad swath of households and the FHA and other government entities did just that.

But the Obama Administration and Congress have not been able to find a path through their fundamental policy disputes about the appropriate role of Fannie and Freddie in the housing market. The center of gravity of that debate has shifted, however, since the election. While President-elect Donald Trump has not made his views on housing finance reform broadly known, it is likely that meaningful reform will have a chance in 2017.

Even if reform is more likely now, just about everything is contested when it comes to Fannie and Freddie. Coming to a compromise on responses to three types of market failures could, however, lead the way to a reform plan that could actually get enacted.

Even way before the financial crisis, housing policy analysts bemoaned the fact that Fannie and Freddie’s business model “privatizing gains and socialized losses.” The financial crisis confirmed that judgment. Some, including House Financial Services Committee Chairman Jeb Hensarling (R-Texas), have concluded that the only way to address this failing is to completely remove the federal government from housing finance (allowing, however, a limited role for the FHA).

The virtue of Hensarling’s Protecting American Taxpayers and Homeowners Act (PATH) Act of 2013 is that it allocates credit risk to the private sector, where it belongs. Generally, government should not intervene in the mortgage markets unless there is a market failure, some inefficient allocation of credit.

But the PATH Act fails to grapple with the fact that the private sector does not appear to have the capacity to handle all of that risk, particularly on the terms that Americans have come to expect. This lack of capacity is a form of market failure. The ever-popular 30-year fixed-rate mortgage, for instance, would almost certainly become an expensive niche product without government involvement in the mortgage market.

The bipartisan Housing Finance Reform and Taxpayer Protection Act of 2014, or the Johnson-Crapo bill, reflects a more realistic view of how the secondary mortgage market functions. It would phase out Fannie and Freddie and replace it with a government-owned company that would provide the infrastructure for securitization. This alternative would also leave credit risk in the hands of the private sector, but just to the extent that it could be appropriately absorbed.

Whether we admit it or not, we all know that the federal government will step in if a crisis in the mortgage market gets bad enough. This makes sense because frozen credit markets are a type of market failure. It is best to set up the appropriate infrastructure now to deal with such a possibility, instead of relying on the gun-to-the-head approach that led to the Fannie and Freddie bailout legislation in 2008.

Republicans and Democrats alike have placed homeownership at the center of their housing policy platforms for a long time. Homeownership represents stability, independence and engagement with community. It is also a path to financial security and wealth accumulation for many.

In the past, housing policy has overemphasized the importance of access to credit. This has led to poor mortgage underwriting. When the private sector also engaged in loose underwriting, we got into really big trouble. Federal housing policy should emphasize access to sustainable credit.

A reform plan should ensure that those who are likely to make their mortgage payment month-in, month-out can access the mortgage markets. If such borrowers are not able to access the mortgage market, it is appropriate for the federal government to correct that market failure as well. The FHA is the natural candidate to take the lead on this.

Housing finance reform went nowhere over the last eight years, so we should not assume it will have an easy time of it in 2017. But if we develop a reform agenda that is designed to correct predictable market failures, we can build a housing finance system that supports a healthy housing market for the rest of the century, and perhaps beyond.

TRID Trials

compliance definition

The Consumer Financial Protection Bureau issued the TILA-RESPA Integrated Disclosure (TRID) Rule which went into effect more than six months ago. The TRID Rule were designed to enhance consumer protections in the mortgage application process.  The mortgage industry has been very concerned about its ability to comply with the rule and has also highlighted the fact that borrowers now face longer waits to close as a result of the new regulatory regime. Many in the industry are calling for changes to TRID, but they are not yet in the offing. As far as I can tell, the main problems with TRID are just transition issues as the massive mortgage industry has to change in many ways, large and small, to comply with the new regime.

Kroll Bond Rating Agency has issued an RMBS Commentary which expects TRID to have only a limited impact on residential mortgage-backed securities enhancement levels. Kroll seems to be taking a reasonable position regarding the industry’s failure to consistently comply with the TRID Rule.

The commentary provides some useful information to those who follow TRID developments. Kroll believes that it “is possible many TRID-Eligible Loans originated in the near term will contain at least one technical error under TRID. Such violations, even if corrected in good faith, may carry assignee liability.” (1) At the same time, Kroll “believes the potential assignee liability stemming from TRID violations is both limited and quantifiable.” (1) It is worth contrasting this measured assessment with the histrionics that the credit rating industry displayed with the assignee liability provisions of many of the state anti-predatory lending laws that were enacted in the early 2000s.

Kroll does draw a distinction between the many TRID errors that are cropping up during this transition time and those that might occur over and over again without correction. The latter, of course, could be a magnet for class actions. That seems to me like a good outcome, particularly where the lender has been made aware of the violations by third parties.

While the mortgage industry has reasonably requested clarification of some aspects of the TRID Rule, the industry itself should be seeking to modernize and automate its processes to address not only TRID-induced changes but also the industry’s 20th century mindset. The modern mortgage closing is far from a paragon of technological efficiency.
